It is formed by the fusion of three pairs of ganglia. It represents the brain and is concerned chiefly with sensory function.

Answer:

The Insect Brain

diagram of insect brainlabelled diagram of insect braininsect brain showing position of foregutdiagram of section through insect brainThe basic insect nervous system bauplan consists of a series of body segments, each equipped with a pair of connected

ganglia, with a paired nerve cord connecting adjacent ganglia in each segment. The ganglia are bulbous structures

consisting of neuron cell-bodies and supporting or glial cells and acts as a local processor or computer. the ganglia are

interconnected by neurons, constituing a computer network. This plan is variously modified in the various types, but in all

cases the ganglia of the head segment form a fused mass, situated above the oesophagus (esophagus) of the gut, and

called the supraoesophageal ganglion. This is connected by a pair of nerve trunks (connectives or commissures) that

course around the oesophagus on either side and join to the suboesophageal ganglion (SOG or SEG) situated beneath

the oesophagus. Many consider only the supraoesophageal ganglion to constitute the insect brain, others (including myself)

consider the SOG as part of the brain.
